What is a Virtual On-Call Phone Number?

New On-Call & Operations Published

A Virtual On-Call Phone Number is a cloud-based telephone number used specifically for incident reporting that is not tied to a physical device. It acts as a permanent entry point for stakeholders, while the "backend" of the number dynamically points to whichever engineer is currently active in the on-call rotation. This allows organizations to provide a single, consistent number to customers while maintaining flexible internal schedules.

Key Benefits of Virtual Numbers

  • Consistency: Customers and internal teams only need to save one number, regardless of how often your team rotations change.
  • Local Presence: Organizations can choose local or toll-free numbers in different countries to reduce calling costs for their users.
  • Privacy: Engineers can receive work-related calls on their personal devices without having to share their private phone numbers with the public.
